Cxle8108 is a PWM control mode switch type DC / DC boost constant current chip. It is used to drive 3W high-power white LED. The current of LED can be adjusted at 500mA ~ 1a by adjusting the external resistance, and the power loss of external resistance can be reduced by 95mv feedback voltage. Cxle8108 has a fixed switching frequency of 1000khz, so low value inductors and ceramic capacitors can be used for peripheral devices.
